Question

I have function like this

typedef vector<vector<string> > vecArray;
vecArray dul();

vecArray dul() {
    vecArray arr = {
                    { "a", "b", "c" },
                    { "a", "b", "c" },
                    { "a", "v", "d" }
                    };
    return arr;
}

i want to return look like bellow string in C++ function

{
{"ffsff","aaaasda","ddaddd"},
{"sfsasda","sdadsfd","asasaad"},
{"adacv","fasfaa","asa","aba"}
}

You can’t construct a vector with an initializer list, as that feature is only available in C++11. You can, with ease though, construct the vector using a 2D array.

vecArray dul() {
    string arrTemp [3][3] = //create 2D array of strings
        {
            { "a", "b", "c" },
            { "a", "b", "c" },
            { "a", "v", "d" }
        };

    vecArray arr; //here's our vector

    //for 3 arrays, push each onto back of vector using the iterator constructor
    for (vecArray::size_type i = 0; i < 3; ++i) 
        arr.push_back (vector<string> (arrTemp [i], arrTemp [i] + 3));

    return arr;
}
